Title
(EN) ADAPTABLE SUPPRESSION TANK LEVEL SENSOR
(FR) CAPTEUR DE NIVEAU DE RÉSERVOIR DE SUPPRESSION ADAPTABLE
Abstract
(EN)
A fire suppressant storage device (20) comprises: a tank (22) having a first port (40), a second port (70), and an interior (32) for storing fire suppressant. A discharge assembly (46) is mounted to the first port and comprises: a discharge valve (48); and a discharge conduit (50). The discharge conduit is at least partially within the interior and has an interior and an exterior. A liquid level measurement assembly is mounted to the second port and comprises: a tube (100) at least partially within the interior and having: an exterior and an interior sealed relative to the surrounding tank interior. A float (120) surrounds the tube and has one or more magnets (130) and having a range of motion. A plurality of magnetic field sensors (152, 154) are along a carrier (150) within the tube interior. The carrier extends from a proximal end to a distal end. The plurality of magnetic field sensors (152, 154) comprise: a first plurality of one dimensional sensors (152); and at least two three-dimensional sensors distally of the first plurality (154)

L'invention concerne un dispositif de stockage d'agent d'extinction (20) comprenant : un réservoir (22) doté d'un premier orifice (40), d'un second orifice (70) et d'un intérieur (32) pour stocker un agent d'extinction. Un ensemble d'évacuation (46) est monté sur le premier orifice et comprend : une soupape d'évacuation (48) ; et un conduit d'évacuation (50). Le conduit d'évacuation se trouve au moins partiellement à l'intérieur et comporte un intérieur et un extérieur. Un ensemble de mesure de niveau de liquide est monté sur le second orifice et est constitué d'un tube (100) situé au moins partiellement à l'intérieur comportant : un extérieur et un intérieur scellés par rapport à l'intérieur du réservoir adjacent. Un flotteur (120) entoure le tube et est doté d'un ou plusieurs aimants (130) et comporte une plage de mouvement. Une pluralité de capteurs de champ magnétique (152, 154) est disposée le long d'un support (150) à l'intérieur du tube. Le support s'étend d'une extrémité proximale à une extrémité distale. La pluralité de capteurs de champ magnétique (152, 154) comprend : une première pluralité de capteurs dimensionnels (152) ; et au moins deux capteurs tridimensionnels distants de la première pluralité (154).
